Question

有一个Zuul应用程序正在由Spring-boot-2.1.4.RELEASE运行。

当我以http://192.168.10.84:8080/app/rest/micro1/inquiry/printCarInquiryList/1?param={%22storeHouseId%22:%22%22,%22storeHouseName%22:%22%22,%22storeHouseType%22:%22%22,%22plaqueSeries%22:%22%22,%22productionYearFrom%22:%22-1%22,%22productionYearTo%22:%22-1%22,%22overallInquery%22:false,%22edited%22:false,%22confirmerCount%22:%22-1%22,%22reportStoreHouseType%22:%22-1%22,%22plaqueNumber%22:%22%22,%22motorNumber%22:%22%22,%22motorNumberOperator%22:%227%22,%22chassisNumber%22:%22%22,%22chassisNumberOperator%22:%227%22,%22storeHouseShowType%22:%221%22,%22havePlaque%22:%22-1%22,%22isFilterByStoreHouseStatus%22:true,%22storeHouseList%22:[%221518691%22],%22goodsStatus%22:null,%22statusId%22:%22-1%22,%22goodsDeleted%22:null,%22formType%22:1,%22searchFilter%22:%22%22,%22order%22:%22%20e.samapelItem.id%20%22,%22pageNumber%22:0,%22pageSize%22:%227%22,%22plaqueType%22:%22-1%22}的身份请求

引发以下异常：

原因：java.net.URISyntaxException：查询中的非法字符索引95： http://192.168.10.84:8080/app/rest/micro1/inquiry/printCarInquiryList/1?param= {％id％22：％22％22，％22storeHouseName％22：％22％22，％22storeHouseType％22：％22％22，％22plaqueSeries％22：％22％22，％22productionYearFrom％22 ：％22-1％22，％22productionYearTo％22：％22-1％22，％22overallInquery％22：false，％22edited％22：false，％22confirmerCount％22：％22-1％22，％22reportStoreHouseType％22 ：％22-1％22，％22plaqueNumber％22：％22％22，％22motorNumber％22：％22％22，％22motorNumberOperator％22：％227％22，％22chassisNumber％22：％22％22，％22chassisNumberOperator ％22：％227％22，％22storeHouseShowType％22：％221％22，％22havePlaque％22：％22-1％22，％22isFilterByStoreHouseStatus％22：true，％22storeHouseList％22：[％221518691％22]，％ 22goodsStatus％22：null，％22statusId％22：％22-1％22，％22goodsDeleted％22：null，％22formType％22：1，％22searchFilter％22：％22％22，％22order％22：％22％ 20e.samapelItem.id％20％22，％22pageNumber％22：0，％22pageSize％22：％227％22，％22plaqueType％22：％22-1％22} 在java.net.URI $ Parser.fail（URI.java:2848）〜[na：1.8.0_181]在 java.net.URI $ Parser.checkChars（URI.java:3021）〜[na：1.8.0_181]在 java.net.URI $ Parser.parseHierarchical（URI.java:3111）〜[na：1.8.0_181] 在java.net.URI $ Parser.parse（URI.java:3053）〜[na：1.8.0_181]在 java.net.URI。（URI.java:588）〜[na：1.8.0_181]在 java.net.URI.create（URI.java:850）〜[na：1.8.0_181]

其中有以下配置：

@Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                connector.setProperty("relaxedQueryChars", "|{}[]");
            }
        });
        return factory;
    }

哪里错了？

Answer 1

解决问题的标准方法是解码一些敏感的字符，例如{等，但是当有一个应用程序包含近1000个JSP文件时，这些字符没有被编码，这种方法要么不可能，要么很难应用到所有使用这些字符的地方。因此，该问题可以通过ZUUL Filter来解决，例如：

@Component
public class CharacterEncodingZuulFilter extends ZuulFilter {


    @Override
    public boolean shouldFilter() {
        return true;
    }

    @Override
    public String filterType() {
        return "pre";
    }

    @Override
    public int filterOrder() {
        return 10000;
    }

    @Override
    public Object run() {
        RequestContext ctx = RequestContext.getCurrentContext();

        Map<String, String[]> qp = new HashMap<>();
        String s = "";
        try {
            s = ctx.getRequest().getQueryString().replaceAll("\\{", URLEncoder.encode("{", "UTF-8"));
            s = s.replaceAll("}", URLEncoder.encode("}", "UTF-8"));
            s = s.replaceAll("\\[", URLEncoder.encode("[", "UTF-8"));
            s = s.replaceAll("]", URLEncoder.encode("]", "UTF-8"));

            HttpServletRequest request = ctx.getRequest();

            CustomRequestWrapper wrapped = new CustomRequestWrapper(request, qp, s);

            ctx.setRequest(wrapped);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

        return null;
    }
}

您需要在URI的查询部分中对{和}字符进行编码。应该分别用%7B和%7D替换它们。
